To all whom it may concern:

main frame and may be driven by any suitable power.

Beit known that I, FREEMAN T. MARTIN, a citizen of It has a sprocketwheel E at one end and a grooved the United States, residing atWinchester, in the county of Clark and State of Kentucky, have inventeda new and useful Improvement in Hemp-Brakes, of which the following is aspecification.

This invention relates to a machine designed for the purpose ofseparating the liber from the stalks and pulpy parts of hemp and thelike, and has for its object to provide an improved machine of the kind,the main or special features of which are a bed provided with ribs onwhich the hemp is laid, and a pair of ribbed rollers which travel backand forth on the material, to break and separate the same.

The machine is illustrated in the accompanying drawings, in which vFigure l is an elevation of one side, designated as the right side, ofthe machine. Fig. 2 is an elevation of the opposite side. Fig. 3 is asection on line 3 3 of the other figures. Fig. 4 is a perspective of thebed plate. Fig. 5 is a plan of the reversing gear.

The mainframe of the machine is indicated at A, the sills being framedand bolted together rectangularly, and it is mounted on wheels O forconvenient transportation.

Upon or above the main frame is a carriage frame B, stoutly built, andmounted upon rollers D, and arranged to travel back and forth on themain frame, from one end to the other, being driven by large spur gearsC,

at opposite sides, which mesh with racks M on the under side of thelongitudinal side pieces of the carriage frame. The gears C are mountedon a shaft eextending across the main frame.

Secured to the inner sides of the mainframe A are angle irons U, uponwhich are mounted the bed plate I-I which comprises side bars, and aseries of cross bars or ribs h, as shown in Fig. 4. Sets of springs 1tare placed between the angle irons and the side bars of the bed plate,to yieldingly support the latter,

The tracks upon which the carriage moves back and forth are mounted onthe side sills of the main trame,

and these tracks have a smooth portion, and also racksl I, along thesame.

The heavy rollers D are journaled in bearings on depending hames bforming part of the carriage frame and braced by braces N. These rollersare located at opposite ends ot the carriage frame and are provided atopposite ends with gears d which mesh with the racks I on the mainframe, and also with plain rims W which roll on' the smooth part of thetrack and so support the carriage and relieve the pressure on the cogwheels. The rollers D are also provided with ribs d which extend acrossthe periphery thereof, parallel to the axis, and cooperate with the ribsh of the bed plate as the rollers pass thereover.

The main drive shaft R extends across under the l i l sprocket wheel Eat the other. On the right side the sprocket is belted by a plain chainbelt Q to a sprocket S loose on a countersha'it s extending across themachine and carrying a fixed pinion F in mesh with one of the gears C. Aclutch indicated in dotted lines at T, between the sprocket S and pinionF enables them to be engaged or disengaged, and the clutch is controlledby a lever X at one end of the machine. On the left side the pulley E isbelted by a crossed chain .I to a grooved sprocket P loose on shaft swhich has at that end another Iixed pinionT) in mesh with the other gearC. The sprocket P clutches with pinion F, the engagement beingcontrolled by lever Z at the end of the machine opposite the lever X.

The shifting levers X and Z are pivoted at 6 to a cross piece 7 underthe frame andare connected by a drag link S to levers 9 which arefulcrnmed on brackets I0 and engage in grooves ll in the hubs of thepulley P and sprocket S respectively.

The machine is fed and operated from both ends, one operator controllingthe drive in one direction, by the lever X, and the other the reverse,by lever Z. The hemp is placed on the bed plate H at each end, and thedrive controlled to roll the carriage back and forth from one end to theother. The ribs h and d are properly positioned and spaced to passbetween each other and the hemp is broken therebetween as the rollerspass thereover, after which the stalks can be easily shaken out and thefiber left free and clean.

I claim 1. In a brake, the combination of a frame having racks along thesides thereof, a bed on the frame having spaced ribs, a carriage overthe traine. rollers journaled in the carriage and having gears in meshwith the racks and 'also having ribs which enter the spaces between saidribs, and means to move the carriage back and forth.

2. In a brake, the combination of n spring-supported bed having spacedribs, and a roller movable back and forth over the bed and having ribswhich enter the spaces between the ribs of the bed.

3. In a brake, the combination with a ribbed bed, tracks along oppositesides of the bed having a plain portion and a cog-ged portion forming arack, a carriage frame movable. back and forth over the hed, and rollersjournaled in the carriage and having' ribs which cooperate with the ribsof the bed, and also having' plain rims which rest on thc plain portionsof the track and a gear which meches with the rack.

l. In a brake, the combination of a ribbed bed, a carriage movable backand forth thereover, and having a rack at each side, rollers journaledin the carriage and having ribs which cooperate with the ribs of thehed, gears at op posite sides of the bed, in mesh with the racks, andmeans to revolve the gears in opposite directions, toreciprocate thecarriage.
